Is there a point where conditions emerge? Conversely, is there ever a time when "under no circumstances" will I change my opinion? There's a bar - it may be high or low, but it's there. 

I love my kids unconditionally. I love my wife unconditionally. I love my parents unconditionally. But...

Could I be the parent of the next Adolf Hitler? Would my unconditional love hold? And if it does, what does that make me?

In a recent documentary I watched, a serial forger and murderer fooled his entire family for many years. Then, before his arrest, he blew up (literally!) two former associates who might expose him. His (ex)wife claims she had no idea. His close associates claim they had no idea. The fraud was, by most accounts, perfect. Until it wasn't, of course. Even after authorities put him in jail, he tried to have folks killed. 

In my life, folks I thought I knew well were involved in dark, nefarious acts. Unsurprisingly, those acts were kept behind closed doors and out of sight. As far as I know, none of the people I love unconditionally fall into this bucket, but I can't guarantee that won't happen.

At the point where more truth emerges, the calculus changes.
